Kurogane Communication

Not even the end of the world can dampen Haruka's spirits! Though a robotic war wiped out all human life over a year ago, Haruka is certain she can't be the only person left alive. And it's not like she's entirely alone – she has her robot family to keep her company! Together, the six of them will travel the world, looking for signs of other humans – and learning a lot about life, love and friendship along the way.
